Sprinkler k factor orifice size

For us this orifice will be a fire sprinkler head or water mist nozzle in a fire protection system, we can use the k-factor formula for almost any rounded orifice. Jan 20- finishes, temperature ratings, thread sizes, and nominal K-Factors for the. Viking sprinklers are available in several orifice sizes with related .

Do not just match the thread size when replacing a. Orifice Sizes are Represented by a “K Factor”. Pressure Requirements for Various-Sized Orifice Sprinklers at Various. Jun 20- The Viking Quick Response Extra-Large Orifice Upright Sprinkler.

Extra-Large Orifice Sprinklers may eliminate the need for a fire pump or reduce the size. Metric K-factor measurement shown is when pressure is measured . The characteristic used for measuring the size of the orifice is called the K-factor, and it represents the mathematical constant relating the flow from the sprinkler . The Upright, Pendent Sprinklers all produce a hemispherical water distribution pattern below the deflector. Water flowing through the sprinkler orifice strikes the sprinkler.

Jan 20- is to know how much water will flow from an open sprinkler. K = sprinkler K factor, a mathematical coefficient of its orifice size p = flowing . While K-factor is used in calculation in other units like that in SI system, the K-factor of a nozzle, such as a sprinkler, a measuring orifice, or even any outlet of a . Mixing orifice sizes of residential sprinklers in NFPA occupancies is allowed as long as the spacing . Selection of orifice size for different sprinkler spacing is important in providing a cost effective design to comply with NFPA 20Edition. An increase in the k-factor of a sprinkler yields a higher flow (gpm), but. This difference is important because the K factor rather than the orifice size is . For K-Factor when pressure is measured in Bar, multiply S. Model F1F1FRUpright Sprinklers (SSU), 5. Globe's Model WS Window Sprinklers are. K-Factor 1for the use in sprinkler systems according to VdS CEA 4001.
